I AM RUNNING FEVER FOR THREE DAYS, SHOULD I GO FOR RT-PCR/RAPID ANTIGEN TEST/CBNAAT?

In the current situation ( April 2021), it is presumed you have Covid 19 infection. Treat accordingly. If available, get RT-PCR test done for COVID 19. Only if RT-PCR test facility is not there, Rapid Antigen Test or CBNAAT may be done.
